What are the different types of clouds?
There are three types of clouds: high, middle, and low. High clouds are found at the highest altitudes, typically around 18,000-25,000 feet (about 5.5-7.6 km) above sea level. They are made of ice crystals and are often called cirrus clouds. Middle clouds are found at altitudes of around 6,500-18,000 feet (about 2-5.5 km) above sea level. They are made of ice crystals or water droplets and are often called altostr clouds. Low clouds are found at the lowest altitudes, typically below 6,500 feet (about 2 km) above sea level. They are made of water droplets and are often called stratus clouds.
